Declaring a new variable referencing a struct stored property variable (Stuct vs Class | Value Type vs Reference Type)

In the Beginning iOS::Object-Oriented Swift::Structs vs Classes video starting at 3:04, Pasan states that a newly declared variable that references a struct stored property variable would be ignored and the original stored property would result.

This is not the case when I attempted to reproduce his statement. Is this a new feature within Swift 4?


struct User {
    var fullName: String
    var email: String
    var age: Int

var someUser = User(fullName: "Johnathan Maravilla", email: "fake@metastry.com", age: 33)

var anotherUser = someUser

someUser.email = "test@metastry.com"

I figured it out. My code was incorrect:

someUser.email = "test@metastry.com"

This line of code was outside of bounds and should have been under


I was also calling the wrong instance when attempting to print and the result was as it should have been based upon what I was calling.

Side note: I found a blog post by Apple, explaining the differences between value types and reference types. it helped me understand the difference a bit more.
